Hey dear friend
1.(x+5)(x+2)
By identity (x+a)(x+b)=x²+(a+b)x+ab
Where, x=x, a=5 and b=2
=x²+(5+2)x+5*2
=x²+7x+10
2.(x-5)(x-5)
=>(x-5)²
By identity (a-b)²= a²+b²-2ab
Where,
a=x and b= -5
=>x²+5²+2*x*(-5)
=>x²+25-10x
perfectly fine pure correct answer
hope it helps you mark me as brainliest and follow me
